摘要
偏苯三酸三辛酯是由偏苯三酸酐：辛醇为１：０．５（摩尔比），在复合催化剂氢氧化铝和氢氧化钠的存在下，１６０～２２０℃酯化１２０～１８０分钟而制得，所得产品酯含量达９９．５％，体积电阻系数为８．４×１０１１Ω·ｃｍ．偏苯三酸三辛酯作为增塑剂应用于电缆料中，拉伸强度为２６．３ＭＰａ．伸长率为２６０％，脆化温度为－３７℃．１００℃下老化７天失重３．１％，保持伸长率９２％．
The Trimellitic anhydride and 2-athyl hexanol were reacted a 160-220℃ for 120-180minute atthe presence of sodium hydroxide and aluminium hydroxide in the mole ratio 1:4,5.The purityof the produdion is 99'5%,the coefficient of resistance per volume is 8.4× 1011ohm cm.
